CVE-2026-5928

A flaw was found in glibc GNU C Library. When the ungetwc function is called on a file stream using wide characters with specific overlapping single-byte and multi-byte encodings, it may attempt to read data outside of its allocated buffer. This can lead to the unintentional disclosure of sensiti...

CVE-2026-5450

A flaw was found in glibc GNU C Library. This vulnerability occurs when an application uses the scanf family of functions with a %mc format specifier, which is used for dynamically allocating memory for character input, and provides an explicit width greater than 1024. This specific combination c...
